TNY289PG Frequently Asked Questions (FAQs)
-
The TNY289PG is a 90W offline switcher IC, but the maximum output power depends on the specific application and design. However, as a general guideline, it can handle up to 65W of continuous output power with proper thermal design and heat sinking.
-
To ensure the TNY289PG operates within its SOA, follow the guidelines in the datasheet for maximum voltage, current, and power dissipation. Additionally, ensure proper thermal design, heat sinking, and cooling to keep the junction temperature below 150°C.
-
The recommended PCB layout and thermal design for the TNY289PG can be found in the Power Integrations application notes and reference designs. Key considerations include keeping the high-voltage nodes away from the low-voltage nodes, using a solid ground plane, and ensuring good thermal conductivity to the heat sink.
-
To optimize the TNY289PG for low standby power consumption, use the built-in low standby power mode, which reduces the quiescent current to around 10mA. Additionally, ensure that the input voltage is minimized during standby, and consider using a low-voltage, low-power startup circuit.
-
Key considerations for EMI filtering and compliance with the TNY289PG include using a common-mode choke, Y-capacitors, and X-capacitors to filter out electromagnetic interference. Ensure that the EMI filter is designed to meet the relevant regulatory standards, such as CISPR 22 and EN 55022.
